…eld the pipe Codex 0.157 printed `clamping SessionEnd hook timeout to 3s in …/agent-sync/…/hooks.json` at every session start. The hook declared 20 s; Codex clamps a SessionEnd handler to 3 s, and Claude Code sizes its SessionEnd wait from the largest handler timeout. - hooks.json declares timeout 3; check_hooks_manifest refuses more, with a self-test plant of the shipped 20 - `release --held` gives back everything the run holds in ONE process; session-end.sh runs it under a 2 s limit instead of whoami plus one release process per key - run_limited's bash fallback (stock macOS has no timeout/gtimeout) left an orphan `sleep` holding the caller's pipe, so $(run_limited 10 …) and `| sed` waited the full limit. session-end took 10.4 s for three leases. The watchdog now polls kill -0 in 0.1 s steps with its stdio on /dev/null Gate: npm test EXIT=0 — validate PASS v1.21.0, SELF-TEST PASS (62 fixtures), claim cell 27, session hooks 13 (7 new), installer 11.
